Ultra high-spec processing performance with quad-core Arm® Cortex®-A15 (1.4 GHz) and quad-core Arm® Cortex®-A7 (780 MHz) CPUs, with 3D graphics and video codec engine.


The RZ/G1H is Renesas‘ top-performing device for general-purpose applications. It is equipped with quad-core Cortex®-A15 (1.4 GHz) and Cortex®-A7 (780 MHz) CPUs, a DDR interface with two 32-bit DDR3 channels, a 3D graphics engine (PowerVR G6400 at 520 MHz), and two dedicated channels of hardware supporting encoding and decoding of full high-definition video. This high-spec processor is also equipped with high-speed USB 3.0, PCI Express, and SATA interfaces and other comprehensive peripheral functions. The high performance of the RZ/G1H allows it to carry out highly-complex graphics and image processing that, such as image recognition and authentication, while processing multiple video streams.
